Read the assertion and reason carefully to mark the correct option ou...
Assertion: Inertia is the property by virtue of which the body is unable to change by itself the state of rest only.
Reason: The bodies do not change their state unless acted upon by an unbalanced external force.
The correct answer is option D, which states that the assertion is false but the reason is true.
Inertia is the property of matter by which an object resists any change in its state of motion. It means that an object at rest tends to remain at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force. However, the assertion states that inertia is the property by virtue of which the body is unable to change by itself the state of rest only. This statement is not entirely true because inertia affects both objects at rest and objects in motion.
The reason provided in the statement is correct. According to Newton's first law of motion, also known as the law of inertia, an object will remain in its state of rest or uniform motion in a straight line unless acted upon by an unbalanced external force. In other words, if no external force is applied to an object, it will not change its state of motion. The bodies do not change their state unless acted upon by an unbalanced external force, which is the correct explanation of inertia.
In conclusion, the assertion is false because inertia affects both objects at rest and objects in motion. However, the reason is true as it correctly explains that bodies do not change their state unless acted upon by an unbalanced external force. Therefore, the correct answer is option D.
